Outcrop studies are often used as analogues to subsurface sedimentary reservoirs, with photogrammetry representing a useful technique to obtain quantitative geometrical data of sedimentary architectures. Digital photogrammetric techniques were used to study fluvial sediments of the Lower Jurassic Kayenta Formation of the western USA. Model‐extracted statistics for channel and sheetflood elements, relevant to reservoir modelling, were compared with 1D and 2D datasets from the same outcrops. Results suggest that the 1D/2D data significantly underestimated element dimensions and ranges in ephemeral fluvial systems. Consequently, this study demonstrates the value of photogrammetric techniques for obtaining statistically relevant and more accurate reservoir modelling input data from outcrops.

摄影测量法在短暂河流系统中生成定量地物数据的应用

露头研究通常用作地下沉积物储层的类似物,摄影测量法是获得沉积物结构定量几何数据的有用技术。数字摄影测量技术被用来研究美国西部下侏罗统Kayenta组的河流沉积物。与储层建模相关的河道和表层洪水要素的模型提取统计数据与同一露头的一维和二维数据集进行了比较。结果表明1D / 2D数据大大低估了短暂河流系统中的元素尺寸和范围。因此,本研究证明了摄影测量技术对于从露头获得统计上相关且更准确的油藏建模输入数据的价值。
